Thanks Dudeman.

But no need to be an ass, and I'm in grade 8.

EDIT: Oh and that's not the way our teacher wants us to do it.

She said.. It HAS to look like this.

3x + 5 = 14
3x + 5 + (-5) = 14 + (-5)
3x + 5 - 5 = 14 - 5
3x = 9
3x over 3 = 9 over 3
x = 3


"Over" = Fraction.

That's pretty much exactly what I did. Plus I answered before doodman, making me superior. :P

2m - 15 = -21 + 8
2m -15 = -13
2m - 15 + 15= -13 + 15
2m = 2
m=1

Haha, I didn't see your answer first.

That's because he's adopted and no one loves him.

Don't listen to that silly little adopted boy.

Haha, I won't now that you've said that.

It's k, the San Fransiscan Jew probably deleted my post and then restored it after you saw his. Silly jew and his wacky antics.

We all know that you're the one responsible for 9/11. Don't go all jew-queda on my ass.

MOAR PROBLEMS-

The air speed of an airplane is 520 mi/h, and it's heading is 110 degrees. The wind is blowing from the south at 15 mi/h. Find the ground speed and course of the plane.

No strung, it's not heading to the WTC.

Haha, I didn't know StrunG was a Terrorist...

Physics eh?


Simply Draw a parrallelogram.

First what you need to do is have your plane be the start point.
Then decide what the ratio of MPH to CM should be, (like...say.. 20 MPH = 1 CM) then draw a line from the plane at an angle of 110 degrees. Make sure that this line's length fits the ratio we just made.
(in this case, the line should be 26 CM long. [520/20])

Now, draw another line from the plane toward north (since the wind is blowing FROM the south). Make sure that the line is the correct length for the ratio we determined. (20/15 = a decimal, but it shouldn't be too small.)

Now, draw a parrallelogram using the lines you just drew.
The total MPH of the plan SHOULD be equal to the distance between the plane (start point) and the farthest corner. (Factoring in the ratio, of course.)





Example:



The Circle is the plane, where the angle starts. The bold lines are the wind velocity (pointing north/up) and the plane's velocity (pointing at about 110 degrees angle).

the unbolded lines are the lines you draw to finish the parralellogram.
and the distance between the start poit and the farthest angle should be the right answer.

Who's da king of Physics NOW, bitches?

whats the square root of an angled penis?

whats the angle?

its flaccid

its hard to tell

NOTpun

It was actually trigonometry. The point being: triangles. Your parralellogram thing would've worked if you formed a triangle from the plane across to the top left corner. Then you can use the law of cosines for the ground speed, and the law of sines for the course. Btw, measure angles from the north! (for whatever reason)

I could do the problem, but I needed it to work out my joke.

Lol, maybe I'll post a pysics problem later. They're funner anyway.

Yeah, I have to write shit about a book.

Nuff said, I finished pretty much most of the book, but not all of it. I kinda...lost it. *anime sob*

If anyone has read Flush, please tell me what happens from say...PG 150.

Edit: PM me 'cause I'll probably forget this thread by tomorrow morning.

Edit: Found it, read 110 pages of it, did a report, and some other shit.

Quote from Lone Wolf

I have no clue how to figure this one out.

Two sisters each wanted to buy a notepad. But when they checked their money, one sister was 2 cents short and the other was 24 cents short. When they pooled their money together, they still didn't have enough money to buy a notepad. How much does 1 notepad cost?

I have no idea how to do this...

25 cents.

25-24=1
25-2=23

23+1 does not equal 25.
